355 mg ≈ 3.55 × 10^-7 t. To convert milligrams to metric tonnes, divide by 1,000,000,000: 355 ÷ 1,000,000,000 = 3.55 × 10^-7.
How to convert milligrams to metric tonnes
t = mg × 1 × 10^-9
- 1 mg = 1 × 10^-9 t (and 1 t = 1,000,000,000 mg).
- Multiply the amount by the factor: 355 × 1 × 10^-9 = 3.55 × 10^-7.
- Answer: 355 mg ≈ 3.55 × 10^-7 t (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000 gives the same result as multiplying by 1 × 10^-9.
